Subject: [PATCH] I2C: BCM2835: Linking platform nodes to adapter nodes
Date: Mon, 25 Nov 2013 09:01:50 +0100	[thread overview]
Message-ID: <529303EE.4080606@koalo.de> (raw)

In order to find I2C devices in the device tree, the platform nodes
have to be known by the I2C core. This requires setting the
dev.of_node parameter of the adapter.

Signed-off-by: Florian Meier <florian.meier-oZ8rN/sblLk@public.gmane.org>

Since the general approach is not easy enough
(see [PATCH] i2c: Fallback to of_node of parent),
this patch adds the required line to the bcm2835 bus.
